Jiang Yuan gave the small thieves in Ningtai County an extended period of freedom, which lasted for a little over a day.

On the second day, the three police officers in the image office couldn't help but become excited when they saw that Jiang Yuan was still working on a normal theft case.

When Jiang Yuan approached, the youngest officer, Gao Jiansheng, said, "Jiang forensic, if you have time, could you help us with a case?"

"What case?" Jiang Yuan asked.

"There are two gangsters from out of town who came here and robbed several women's bags in front of the bus station. The victims reported the incident, and we have found the footage, but we can't clean it up." Gao Jiansheng had already prepared the pictures and took them out as he spoke.

By "can't clean it up," he meant that the noise reduction wasn't done properly.

As the foundation of image enhancement, this was the simplest method and the most commonly used one in Ningtai County's image department.

With just a glance, Jiang Yuan saw that Gao Jiansheng and the others had already extracted the image of the suspects from the video.

However, due to technical limitations, they couldn't obtain clear facial features or other identifiable characteristics.

"Let me try." Jiang Yuan sat down in front of the computer and started operating it directly.

"Okay." Gao Jiansheng happily gave up his desk and computer to Jiang Yuan and sat in the corner, taking out his phone and playing with it.

This was the difference between Gao Jiansheng and Wang Zhong.

Both of them were technicians at level 1, but Wang Zhong had a strong motivation to learn. Whenever Jiang Yuan was doing fingerprint analysis, Wang Zhong always found opportunities to watch.

Gao Jiansheng was different.

As long as he could get through the day's work, he didn't care how he did it.

As for improving his skills, Gao Jiansheng occasionally had such thoughts, but usually, after watching Jiang Yuan's operation for a minute, he would give up.

Now, he couldn't even be bothered to watch for a minute.

This was not only due to their different personalities but also related to their technical paths.

Wang Zhong specialized in fingerprints. Although there were some advanced techniques in this field, there were only a few. The rest required diligent accumulation and luck.

The field of image investigation was different. Besides the simplest software methods, everything else was advanced. Various Lagrange Fourier techniques required strong skills and talent.

Gao Jiansheng's personality was one aspect, but image investigation was indeed difficult.

Regardless of the reasons, Gao Jiansheng had already determined his development direction - becoming the number one image investigator in Ningtai County.

"Let me know when you're done." Jiang Yuan stood up and Gao Jiansheng's computer suddenly became noisy.

The advantage of working in the image department was that their computers had good configurations, and they could handle post-processing themselves, saving Jiang Yuan a lot of effort.

Forensic office.

Wu Jun was playing with a hanging plant out of boredom. When he saw Jiang Yuan return, he immediately asked, "Why did it take so long? What are they bothering you with now?"

"There's a case of car robbery. I enhanced the images a bit." Jiang Yuan answered briefly.

"I think you're planning to take over all the work in the criminal investigation team." Wu Jun glanced at him.

Jiang Yuan smiled, "I've seen forensic experts in other countries doing multiple jobs, haven't I?"

"If I may say something incorrect as your master, you're being too ambitious," Wu Jun sighed.

"What else can I do? Start a business?" Jiang Yuan thought about the balance in his bank account and found it uninteresting.

Besides, he wasn't really interested in doing business. Most people in Jiang Village felt the same way. After being a landlord for a long time, seeing tenants come in with hope and leave with exhaustion was quite disheartening.

The most pitiful businesspeople were those who appeared extremely shrewd but still ended up losing everything after calculating and strategizing at every step.

Although Wu Jun didn't have much money, he could understand the feelings of people in Jiang Village. "Then, why not take some time to rest?"

"I don't have time." Jiang Yuan shrugged. "If I had time, I would sentence that guy who loves to kick while walking to another seven years."

Wu Jun's thoughts were instantly diverted. "You know, when I was young, we had someone in our bureau who did gait analysis. But it mainly focused on footprints. It was best if the ground was soft. After the suspect ran away, we could determine their walking posture characteristics through on-site investigation. Sometimes we even followed the footprints directly..."

Jiang Yuan listened without saying a word. He actually understood a bit about this technique, but it was useless now.

Today, not to mention in the city, even in towns and villages, the main roads were all paved. Most people's rooms were tiled or had wooden floors, and even the yards were similar.

It could be said that the technique of tracking criminals through footprints on soft ground had become increasingly ineffective with the expansion of infrastructure.

As Jiang Yuan chatted with Wu Jun, he reopened the video and started watching.

Huang Qiangming's call came in at the opportune moment.

"Jiang Yuan, go to Longli County again." Huang Qiangming chuckled and said, "There's been a murder case in the countryside over there. The crime scene is covered in blood, and they can't find any clues. It's been almost two days. Go take a look."

Jiang Yuan was a bit surprised and repeated, "Go to Longli County?"

The captain of the criminal investigation team in Longli County, Hou Lejia, didn't get along well with Huang Qiangming. Whenever they met, they would compete with each other. Moreover, Jiang Yuan had just returned from the city, so Huang Qiangming wouldn't want to let him go so soon...

Huang Qiangming coughed twice and said, "After all, it's a murder case. If we can't solve it now, it will be even more troublesome later."

He gave some more details and then hung up the phone.Jiang Yuan stood up, picking up the keys with a hint of confusion. "Master, I'm heading to Longli County today, but I'm not sure about Captain Huang..."

"They must have offered you a good deal," Wu Jun, who understood the situation all too well, said nonchalantly. "When a murder case arises and no leads can be found after two days, they're bound to panic. And when they panic, they're likely to make rash offers. They must have promised Captain Huang quite a bit."

"What could Longli County possibly offer?" Jiang Yuan wondered.

"Even a few dog exchanges wouldn't be bad," Wu Jun suggested. "Hou Lejia treasures their county's Blackie. It's not easy to borrow him for ordinary cases."

"Don't we also have a dog?"

Wu Jun glanced at Jiang Yuan. "Blackie is quite impressive, clearly smarter than our Strong. Alright, if you've agreed to go, you should get going. It'll be nightfall if you delay any longer."

"I'll ask Wang Zhong to come with me," Jiang Yuan said, unwilling to go alone. Unfortunately, Mu Zhiyang was still recovering from his injury, so he could only ask Wang Zhong to accompany him.
